Title: Flash light circuit with thyristor - is bridged by antiparallel diode and capacitor limiting flash duration
IPC: H05B41/32
Filed: 1973-08-02
Abstract: The flash light circuit has a thyristor in series with the lamp across the supply. The thyristor is bridged by an antiparallel diode. The duration of the flash is limited by the series combination of a second thyristor, inductor (11) and capacitor (7), all coupled across the first thyristor (with both thyristors having the same conduction direction, i.e. coupled cathode to cathode). The first thyristor gate is connected to a two-resistor voltage divider which is connected at one end of the two thyristor cathodes (i.e. to the negative supply pole) and at the other end over a capacitor to the junction between first capacitor and inductor. This same junction is coupled over a resistor to the positive supply pole.

Patent DE-2414585-A1 (DE)
Title: Shock absorber for instrument mechanism - has tapered pin penetrating centre hole of spiral spring on impact
Inventor: KUELZER PETER
IPC: B41J19/04
Filed: 1974-03-26
Abstract: A damping mechanism for instruments consists of a flat spiral spring coil and a tapered pin which is attached to the moving mass. In the relaxed state, the spiral spring has a centre hole which is about equal to the smaller diameter of the tapered pin. When the taper pin of the moving mass hits and penetrates the centre of the spiral spring, its kinetic energy is absorbed by friction and spring deformation. After impact, the deformation energy causes the spring to contract, thus resetting the moving mass without rebound. The mechanism is as far as possible proof against external influences such as variations in temperature.
Patent DE-2418826-A1 (DE)
Title: Heating chamber with forced air circulation - for testing purposes, thermal processing or containing a controlled atmosphere
Inventor: SCHINLE FRIEDBERT DIPL ING
IPC: B01L1/00
Filed: 1974-04-19
Abstract: In a chamber having a variable-area air outlet and in which a centrifugal fan is arranged, whose shaft extends through an opening in the chamber wall, the size of the latter opening is such that, during operation, air is drawn along the shaft and passes through orifices in the low pressure region of the impeller of the fan. The impeller has blades on one side only. Used as heated chambers with forced air circulation, e.g. paint drying ovens. Single sided impeller occupies min. space in chamber. Stable air flow and temp. distribution are achieved since the sum of the vols. of the air drawn in and the air circulated inside the chamber is constant. Separate air inlet is not required. Efficient mixing of the fresh air with the recirculated air is achieved.
Patent DE-2422557-A1 (DE)
Title: Pipe bends of rubber-plastics material - made by vulcanising preform supported by inner mandrel, and with a sleeve around end section
Inventor: GIELER JOACHIM

Patent DE-2444544-A1 (DE)
Title: Contact free gas seal rings with gas barrier - have curved radial grooves to produce aerostatic axial force
Inventor: KOTZUR JOACHIM
IPC: F16J15/34
Filed: 1974-09-18
Abstract: The seal arrangement for a rotating shaft has a rotating ring (1) which is attached to the shaft, and a stationary ring (2) which is axially next to it located in a seal chamber (10). The contact face of the stationary seal ring has curved radial grooves (9) which produce an axial aerostatic force when the shaft rotates at its design speed. This keeps the two sealing rings apart without the need for a large supply of sealing gas. When starting the shaft rotation, sealing gas is forced between the two seal rings to keep them apart and maintain the seal effective at low rotational speed.

Title: Diesel fuel and heating oil metering - by secondary counters coupled to main volumetric flowmeter and to dye container
Inventor: SCHMIDT HANS
IPC: B67D7/04
Filed: 1975-05-23
Abstract: A volumetric flowmeter for the issue of dyed fuel oil for heating and clear diesel fuel for road vehicles from the same gas oil line has, in addition to the main counter, two separate secondary counters. One is acturated by a solenoid valve when the dye admixt. line is opened and records the heating fuel oil vol., the other is in engagement with the main counter when the dye admixt. pipe is cut off and records the Diesel fuel. This saves the expenditure and the space for two separate volumetric flowmeters. A simple attachment provides a printed record of the issued oil vol.
